If you are thinking about replacing your old boiler, you need to review the types of boilers that are featured on the market today. Boilers are featured as combi boilers, system boilers, and regular boilers.
A combination boiler is also called a combi boiler. This type of system combines a central heating boiler and high-efficiency water heater into one unit. The boiler’s water is heated from the mains as soon as the user switches on the tap. As a result, a hot water storage cylinder is not needed nor is a cold water storage tank required for operation.
System boilers operate by using a cylinder to store hot water. However, the primary hot water and heating components are incorporated into the boiler. As a result, this type of boiler can be quickly installed. In addition, you do not have to include a tank in the loft. Therefore, these types of boilers – servicing, replacements and repairs in PL3 can be combined with solar water heating systems. In addition, standard boilers are often used in homes with limited loft space or no loft space at all.
Regular boilers—also called conventional boilers—are installed in homes that have an existing hot water and heating system – one that is connected to a separate cylinder for the hot water. These boilers, which require a cold water storage tank in the roof space, also need a tank for preserving the water level for the unit’s central heating.
What you choose in an upgrade will therefore depend on your water heating and central heating preferences and needs as well as your requirements in a design.
